Title: Method for generating and screening useful peptides
Inventor: VENTON DUANE L
IPC: C07K14/705
Filed: 1992-08-20
Abstract: The invention allows the generation and screening of a large population of peptides for the presence of peptides which bind a particular macromolecule or macromolecular complex with high affinity, and further allows the favored net synthesis of analyzable quantities of such peptides, by using as the "trap" a macromolecule or macromolecular complex for which binding of the peptide is desired. The starting mixture is preferably spiked with a peptide having some affinity for the target macromolecule so that mutation of the spike or "lead" peptide is favored.

Title: Downhole activated system for perforating a wellbore
Inventor: WILSON DENNIS R
IPC: E21B17/10
Filed: 1992-09-11
Abstract: This invention relates to a method and apparatus for perforating the formation (F) in a wellbore (W) wherein the wellbore is established for the production of hydrocarbons. The formation is perforated by explosive material carried in pistons (50) which are carried within either the pipe casing (60) bathe collars or moth and remain generally within the maximum outward profile of the pipe string so as not to interfere with the movement and placement of the pipe string in the wellbore. The pipe string may be rotated, reciprocated and circulated which enhances the ability of the installer to place the pipe string in a deviated or long reach wellbore: Once the pipe string is in place, the pistons may be deployed by one of several methods such that pistons mounted in openings in the peripheral wall of the pipe string move outwardly with sufficient force to move the pipe string way from the walls of the wellbore sufficient to form a complete annulus for cementing. Once the wellbore is cemented the explosive charges (671) in the pistons may be detonated to perforate the formation adjacent the piston.  The charge may be particularly designed to focus the explosion so that an extensive perforation extends away from the pistons so that the formation is opened up for production of hy-drocarbons.

Abstract: Un ajout au tableau de bord et ou au système de communication pilote-machine de l'hélicoptère pouvant délancher surement l'ouverture d'un parachute en situation d'urgence, en particulier en cas d'arrêt de Moteur. Une boite à Parachute, de forme aérodynamique contenant le (ou possiblement les parachutes ) attaché à l'arbre de rotation des palles élévatrices, mais isole de sa rotation par possiblement un roulement, laissant la boite à parachute livre de rotation que ce n'est la force de la friction et du vent. Au déclenchement radio, commande par le pilote, de l'éjection de la boîte a parachute, la parachute se trouve libre de s'ouvrir et vient donc agir en plus des palles au ralentissement de la chute. Le choix des meilleurs parachutes sur le marché viendra ajouter à la sécurité du pilote et des passagers. Un autre dispositif radio permettra le larguage du parachute, au cas où le pilote réussirait à repartir le moteur et que le parachute devienne ainsi indésirable. Les dispositifs radios seront des dispositifs émetteurs récepteurs à faible intensité. Toutefois pour ne pas nuire à d'autre appareils inclus chaque hélicoptère aura son code de fréquence émetteur-récepteur de façon à ce qu'un pilote ne largue pas le parachute de l'hélicoptère qu'il côtoi. Le larguage du parachute ne pourra toutefois être enclenché à moins que le parachute n'ait déjà été déployé. La réception de quatre fréquences simultanément opérera un déclanchement tel une clef ouvre une serrure.

Title: Projectile and launcher toy
Inventor: ROBINSON ALLAN B
IPC: A63H27/00
Filed: 1994-04-14
Abstract: The toy is composed of a projectile and a tube for launching the projectile into the air. The projectile has a pair of wings symmetrically disposed about a longitudinal axis . The leading edges of the wings normally extend outwardly at an oblique angle from a nose which defines the forward end of the projectile. In that position the projectile will fly through the air.      The wings are spring-biased into the position for flying.      When a manual force opposed to the biasing means is applied to the wings, they fold inwardly with resulting pivoting of the leading edges toward each other. When the wings are closed the projectile is in a pre-launching position.      The projectile is launched into the air by means of a tube which is hollow and open at one end through which the projectile exits from the tube.

Title: Radio-cell extension
Inventor: GOEDECKER REINHOLD
IPC: H04B7/26
Filed: 1995-01-03
Abstract: In cellular radio networks with TDMA transmission, the maximum signal propagation time inside a radio cell limits its propagation to a maximum radius, e.g. to 35 km in the known GSM.  To extend the radio cell, the invention provides a fixed base station (BTS) with a TDMA radio receiver (RX) and an additional TDMA radio receiver (RXe), which receives lagging TDMA radio pulses from mobile stations (MS3) that are positioned outside of the radio cells (C).  In this way, the fixed base station (BTS) supplies an extended radio cell (Ce), in which however only the maximum signal propagation time corresponding to the maximum expansion of the (small) radio cell (C) requires compensation.

Inventor: EL DESSOUKY AHMED A
IPC: B21J15/20
Filed: 1994-08-31
Abstract: A light-weight and compact hand actuated hydraulic tool (20) for the setting of fasteners (172) having a sleeve (174) and stem (170) is disclosed. The tool comprises a housing (22, 222), sleeve engaging nose piece (44, 244) connected to a piston (43, 243) which is slidable in the housing (22, 222), a fluid reservoir (34, 234), handoperated pump lines, and a drawbolt (52, 252) which has stem gripping jaws (60, 260) connected thereto. The stem (170) of a fastener (172) is gripped by the jaws (60, 260), and the sleeve (174) of the fastener (172) is engaged by the nose piece (44, 244). In an initial stage, a pump plunger (58, 258) compresses liquid in first and second chambers (102, 106 and 302, 306) into a piston chamber (116, 316), which affects movement of the housing (22, 222) and drawbolt (52, 252) in relation to the piston (43, 243), pulling the stem (170) in relation to the sleeve (174). As the pulling force increases, and thus the necessary hand pumping force, pressure in the piston chamber (116, 316) opens a valve (124, 129 and 348), allowing fluid in the first chamber (102, 302) to return to the reservoir (34) so that only the second plunger chamber (106, 306) is used to compress the liquid into the piston pressure chamber (116, 316), lessening the force necessary to actuate the pump lever (88, 288). In one arrangement, a pilot piston (332) that opens the valve (348) includes an internal relief valve (338) that allows liquid in the piston chamber (316) to return to the reservoir (34) in response to predetermined maximum piston chamber pressure or in response to manual pressure.

Patent CA-2147817-A1 (CA)
Inventor: WERTHEIMER HARRY P
IPC: F02D41/32
Filed: 1995-04-25
Abstract: According to the present invention, an apparatus and method for controlling injection timing and power balancing in a gaseous fuel engine with an electronic control unit and a shaft encoder is disclosed. The engine includes an engine block having at least one cylinder with an exhaust port and a cylinder head. A fuel injector and a spark plug is seated in the cylinder head and the injector has a valve which separates the fuel in the injector from the cylinder. A piston reciprocates in each cylinder and is attached to a connecting rod. The rod connects each piston to a crankshaft which converts the motion of the piston to rotary motion. The shaft encoder is connected to the crankshaft and monitors the revolutions of the crankshaft. The electronic control unit is coupled to the shaft encoder and to each of the fuel injectors. The method in accordance with the invention includes several steps. First, a working injection time setting the time for each fuel injector to start an injection of fuel into the cylinder is retarded to an initial injection time. Next, the speed of the crankshaft is measured and compared against a first preset limit. The working injection time is advanced at a predetermined rate, if the monitored speed exceeds the first preset limit. When the working injection time is advanced to be equal to or less than a programed function of speed, the working injection time is set to the injection time calculated from the programmed speed function. The method may also involve establishing a working pulse width for each cylinder, measuring an index of the power output in each cylinder, calculating a balancing factor in response to the measured index, and adjusting the working pulse width in response to the balance factor for each cylinder.
